You'll want to use it all day: Weather in the terminal

One command and you can get the weather in any terminal:

curl wttr.in

How awesome is that?

The project and the documentation is available on GitHub. In reality you can do a number of things with this API

curl wttr.in
curl wttr.in/Copenhagen
curl wttr.in/:help
curl wttr.in/Copenhagen?format=3
curl v2.wttr.in # my favourite
curl wttr.in/:help

All in all, great project, really useful tool, I use it every day. Hope you find it useful too.
